VS2010 - Connect To SQL Using Trusted Connection In Connection String
Aug 10, 2011
I have an ASP.Net website running on IIS7. The Application Pool is set to ASPv4 Classic.
Authentication Mode is set to ASP.Net Authentication & Windows Authentication
My question is, when I want to connect to SQL using a "trusted connection" in the Connection String, what user will actually be passed into SQL?
I thought it would pass my logon details, but it is coming back with an NT AUTHORITYANONYMOUS LOGON error, which seems to point towards it not passing in my logon.
I have a db connection string 'ApplicationServices' defined in the connectionString section of web.config and 3 Entity Framework connection strings which have the provider connection string attribute with the same connection string as the one in 'ApplicationServices'. Is there a way to reference connectionString in 'ApplicationServices' for the provider connection string attribute of the EF connection string in the web.config, rather than providing the connection string all over again?
be it's a wrong place to ask the following question. Sorry for that. Our hosting provider has recently upgraded their database server from Sql Server 2005 to 2008 and I'm getting errors to connect with remote server from my development machine. Error Message "Invalid connection". Tried to find solution on net but couldn't find it.I'm using .Net 1.1. Though we've updated versions 2.0,3.5 & 4.0 but due to some certain circumstances I've no way to update it. It's a web based project. The following connection string works fine for Sql Server 2000 & 2005 but not for 2008.<add key="ConnectionString" value="Data Source=Remote Server's domain name;Initial Catalog=database name;User ID=user name;Password=surround;Persist Security Info=True;Pooling=false;Connect Timeout=45;" />Here Remote Server's domain name indicates to remote db server like: test.mysite4now.comdatabase name for example: test_surrounduser name like test_surroundpassword: surround.Can anyone inform me what's wrong with the above connection string to connect to Sql Server 2008.
My web service app on my Windows XP box is trying to log in to my sql server 2005 database on the same box. The machine is part of a domain. I am logged in in the domain and I am an admin on my machine. I am using Windows Authentication in my connection string as in "Server=myServerAddress;Database=myDataBase;Trusted_Connection=True". SQLServer is configured for both types of authentication (mixed mode) and accepts remote connections and accepts tcp and named pipes protocols. Integrated authentication is enabled in IIS and with and without anonymous access. 'Everyone' has access to computer from network setting in local security settings. ASPNET is a user in the sql server and has access to the daatabase. user is mapped to the login.
The app works fine for other developers which means the app shouldn't be changed (It's not new code). So it seems it's my machine which has an issue.
I am getting the error "Login failed for user ''. The user is not associated with a trusted SQL Server connection" Note the blank user name. Why am I getting this error when both the app and database are on my machine? I can use SQL Server authentication but don't want to. I can connect to the database using SSMS and my Windows credentials.
It might be related to setspn, kerberos, delegation, AD. I am not sure what further checks to make?
when i am trying to test my webpage i get this message : " Login failed for user ''. The user is not associated with a trusted SQL Server connection. " idon`t know what to do with because it`s my first webapp
i have a dropdownlist contaning years..now i want to connect my database by dropdown selection.if i select 2013 it will connect 2013 database ,if i select 2014 it connect 2014 so on..
just for my testing purpose i know i can define both the connection's outside in a single web config file by different name's and access them in my front end according to it but what if i want to have seprate for both connection's web.config situation is like this see image so i want to access my connections from second web config file how i can do that.
I am preparing for an Access2007 db conversion at the beginning of the year and would like to know what the best process would be for connecting to the sqlserver2005 database. I have read about adding the connection string to the web.config file. I have also read about using ADO.NET and put the connection information into a class and not the web.config file.
I would like to hear from others as to what you have used, are using, or plan on using for a webapp (vs2010), and why so I can get an understanding.
I'm using Visual Studio 2008, and my database is SQL Server 2000.
I want to add a connection to the Server Explorer in VS. The Data source is Microsoft SQL Server (SqlClient). After entering in all my information and I click Test Connection, it is successful.
But when I click OK, I get the error:
Unable to add data connection. ExecuteScalar requires an open and available connection. The connection's current state is closed.
I am trying to use Windows Authentication in my asp code. I have read / tried all answers on the web but couldnt my page to connect to sql. I m using classic asp.
My conn string looks like :
OCONN.OPEN ("PROVIDER=SQLOLEDB; DATA SOURCE myserver; INITIAL CATALOG=nrth; Integrated Security=SSPI; trusted_Connection=yes")
but I mgetting error

I have an ASP.net web service application that connects to a Progress OpenEdge 10.1B database via ODBC. My development machine is XP Pro and runs everything fine. I am now moving the application into a test environment. The test machine is also XP Pro. It matches the dev machine except for that the Progress Server is not running locally. I am able to run the project out of VS2010 and the web service makes the ODBC connection and returns the data without error. When I deploy the application to IIS (which is running locally) the ODBC connection fails with this error: *System.Data.Odbc.OdbcException: ERROR [IM003] Specified driver could not be loaded due to system error 126 (OpenEdge 10.1B driver).*
We recently launched a new web site.there are roughly ~150 users active during peak hours.During peak hours,we are experiencing an issue every few minutes,the exception text is listed below.
System.Web.HttpUnhandledException: Exception of type 'System.Web.HttpUnhandledException' was thrown. ---> System.Data.SqlClient.SqlException: The client was unable to establish a connection because of an error during connection initialization process before login.
Possible causes include the following: the client tried to connect to an unsupported version of SQL Server; the server was too busy to accept new connections; or there was a resource limitation (insufficient memory or maximum allowed connections) on the server.(provider: Named Pipes Provider, error: 0 - No process is on the other end of the pipe.)
Our data access layer calls various DataTableAdapters using the following syntax.
EDIT
Yes, da is the name assigned to the DataTableAdapter. There is no connection.Open() because the DataTableAdapter takes care of all that, right?

I try to connect sql server 2005 through OBDC connection bt i face a error, i face this error

I previously used a datasource and a connection string to connect to my database on sql server and all orked fine. The connection string was saved in my web.config file and is: ....
I am using VS2008 and oracle 10g ODP.Net. The oracle database that I used in the connection is working and tested it using sql plus.The connection string when used in a GriDView works perfectly. Now when I created a new listview control with the same connection it gives an error.Database schema could not be retrieved for this connection. Please make sure connection settings are correct and the database is online
Object reference not set to an instance of an object at VSDataObjectSupport (478,6)
In my DAL i have more than 100 methods/Function, each and every method am opening the sqlconnection and closing the connection, this is taking too much of time to establish the connection at every time. So what i expect is one common class will create the SqlConnection that will check if the connection is Broken or Closed then create the connection again else return the connection, how to do this(Also i would like to apply ConnectionPooling).
I have VS 2010 professional. I am trying to open "ASP.Net Configuration" through Project -> ASP.Net Configuration.
It pops up the Notification about the ASP.Net Development Server localhost but doesn't open ASP.Net Configuration in the default browser.I clicked on the Root Url (by double clicking on the 'development server' at the right bottom from Notification Manager).
It throws following error
"An error was encountered. Please return to the previous page and try again."
Clicking on "How do i use this tool".It opened page with error.
on VWD 2005 this code works fine, but on 2008 it says I haven't created an instance of the object. I want to convert the object connString (a connection string) into a string.
'This acceses the virtual directory web.config file for connection strings 'We have to convert the object to a connection string Dim rootWebConfig As System.Configuration.Configuration rootWebConfig = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("/VirtualDirec") Dim connString As System.Configuration.ConnectionStringSettings connString = rootWebConfig.ConnectionStrings.ConnectionStrings("ConnectString1") Dim strConnString As String = connString.ToString().......
I'm using an ODBC connection to connect a SQL 2005 database to my ASP.NET app in Visual Web Developer Express. I'm finding that the expected functionality that tutorials review does not work for ODBC connected databases the same way as it does for SQL databases created in the Web Developer. For example, I can't use stored procedures because the option to create one is disabled in the Web Developer, and if I create the stored procedure in SQL Server Management Studio Express, it doesn't show up in Web Developer because Web Developer only finds the system stored procedures, not the user-defined ones. I've seen other cases as well where database management options in Web Developer don't work with ODBC databases.
Am I missing something in my setup, or is there an inherent limitation with ODBC connected databases? Or, is this a limitation with using the Express versions of these development tools?
I have an ASP.NET project which gives me the following exception if I try to run it Where should I "call" it before I can use it ?There is no global.asax in my solution
Project 1: Web Application (.aspx/.ascx/.cs/)* Project 2: Class Library (has one static class, Repository.cs, which is full of static methods used to put/get data to/from DB) Project 3: Web Service (allows few of the mthods of the Repository to be used via WebService)
Conditions:
There will be about 10 copies of Project 1 (WebAppliation) runngin on IIS each for a seperate client.I want each copy of Project 1, and the Web Service to read/write data from/to DB via Repository only. So all 11 Projects (10 Project 1, and 1 Wb Service, will be using repository as DAL)Questions1) Where shall i put the connection strings??? because each web application will have its own connection string, i cant save it in repository. And if i keep it at the web.config of each project, then what is the best way to pass it to repository?
2) Repository.cs is a static class with all static methods, is this a good approach? Should it be static? or should i not make it static in order to allow creationof objects of Repository.cs. (this way may be i can also send connection strings to the objects of repository, in whatever project required...???)
